The present invention relates to textile dyeing and more particularly, in part, to..a method of distinguishing and identifying individual pieces of textile materials, such as skeins, cloth, etc., which are dyed together with many other pieces in a common vat of dyeing substance. It also relates in part to means for maintaining lines of division in textile fabrics throughout the dyeing process.

One of, the objects of the present invention is to provide a tracer or indicator for skeins and cloths which are to be dyed in mass form. The indicator or tracer should be of such material that it is unaffected by the dyeing substance to which it is subjected.

Another object of the invention is to provide identifying or distinguishing means which are pliable, strong, and which may be easily handied and aflixed and removed.

Another object of the invention is to provide a tracer or indicator which may be incorporated into the warp or the fill, or the selvage edge of a piece of cloth, this tracer being of a material which remains unaffected by the dye applied to the material, and thus may serve as an indicator and identifying mark throughout the entire dyeing process. These marks may also be used to designate lines along which the material is to be cut.

At the present time paper tags or the like are attached to each individual skein, identifying it and indicating the procedure through which the particular skein is to pass. Such tags have proved unsatisfactory, however, owing to the large amount of work involved in tagging each individual skein.

Ordinary textiles are unsatisfactory as indicating yarns or means for the skeins and cloths owing to the fact that they take on the dye and become obliterated or indistinguishable.

In the dyeing of cloths, it is common at the present time to separate the selected pieces of cloth from other cloth while in the vat, and then after they have been dyed, they are carefully taken out and retagged with the information as to weave count, etc. Such a procedure, however, is difiicult and requires a large amount of work of retagging, and it also involves the everpresent hazard of mistakes which are easily made with this system.

Other objects and advantages of the present invention will become apparent from the following description taken in conjunction with the drawing. in which:

Fig. 1 is a perspective view of a skein of textile material, bound together with a leesing yarn of fibrous glass as an indicator and tracer;

Fig. 2 is a woven fabric of textile material,

Fig. 4 is a diagrammatic fragmentary crosssectional view of the fabric shown in Fig. 3, the section being taken along the line 4-4; and

Fig. 5 is another fragmentary perspective view of a woven fabric showing a plurality of glass yarns woven in the selvage edge thereof for identifying purposes.

The present invention broadl consists in the application of fibrous glass yarn to the textile dyeingart for purposes of identification of the textile yarns, skeins, and fabrics.

Yarns of fibrous glass may be made of any desired weight and thickness. Fibrous glass may be twisted into yarns and woven into cloth and generally fabricated on the standard textile machine. The glass wool fibers may be fabricated by an apparatus such as disclosed in the Slayter and Thomas Patent 2,133,236. Mechanically spun fibers may also be used, and these may be mechanically spun onto a spool or drum 3 from an apparatus similar to that shown and described in Patent 2,133,236, the pulling taking place at a very high speed, but the gaseous blast being at a relatively low pressure and force to serve primarily as a cooling medium for the 85 fibers of the glass stream in order to permit attenuation to a very high degree without breaking the filaments. If, however, the fibers are attenuated solely by the means of a gaseous blast as shown in Patent 2,133,236, they may be deposited upon a traveling conveyor or accumulated upon a surface and then drafted therefrom in the form of a sliver, which in turn may be drafted and twisted into yarns, threads, etc.

Yarns of glass may be handled on the conventional textile machinery. They may be knotted and the cloths woven therefrom may be folded and creased without splitting. The glass is of such a character that dyes ordinarily used in the textile art will not adhere thereto and change the color thereof but will remain clear and bright and readily distinguishable from the dyed organic textiles. If desired, glass fibers and yarns may be produced of different colors and these also will be unaffected by the dyes owing to the inherent nature of the glass. Various combinations through a particular procedure, may be wrapped with a leasing yarn I l of one predetermined kind or color, as, for example, a plain white glass yarn, and all thoseskeins which are to pass through a different procedure subsequently may be wrapped with a glass leesing yarn ll of a different type, such as a double wrap of leesing yarn, or a combination of a red and a white glass yarn, or any other one of an infinite number and variety of combinations of glass yarns. The skeins then may all be dyed together and each one of them may be identified and distinguished at any stage of the dyeing process. In practice, the identification of these slreins may be facilitated for the operator by means of instruction sheets which indicate the procedure which each group of skeins having its particular type of glass yarn II is to pass through.

Referring now particularly to Fig. 2, I have shown a strip of interwoven cloth l3 of standard textile fabric which is to be dyed a. particular color. Along the sel'v'age edges thereof, I may provide a fibrous glass yarn serving to identify this particular piece of cloth for dyeing purposes. Thus when a multiplicity of these cloths l3 are placed together in a single vat, they all may readily be identified and distinguished from others by the color of the glass yarn which remains unaffected and readily stands out from the dyed fabric.

In Figs. 3 and 4 an interwoven fabric 5 of conventional organic textile -material has been shown, although comprising fill yarns l6 offibrousglass spaced at predetermined intervals and extending transversely across the fabric. The fill yarns l6 serve as identifying lines of division which indicatewhere the fabric is to be cut or folded after the dyeing process. Heretofore when bolts of cloth were dyed, it was necessary prior to cutting to measure the cloth. The use of the glass yarns l6 serves as a ready identification to indicate where the materialis to be cut.

serve as identification or lines of cutting in the longitudinal direction of the fabric. Glass yarns Warp yarns I 'I may also be used in order to to that Fig. 5 illustrates another embodiment of the invention in which a fabricill of conventional organic textile material has interwoven along the selvage edge thereof, a plurality of fibrous glass yarns 2| adapted to serve as indicators or identifying means for the fabric during the dyeing process. The operation of such yarns is similar to that illustrated and descr'ibed in connection with Fig. 2, a plurality of-yarns being used in order to increase the number of combinations of identifying yarns. These may be of diii'erent color if desired. v

Various modifications and variations may be resorted to in the present invention without departing from the scope and spirit thereof as defined in the appended claims.

I claim:

1. The method of identifying and tracing organic textile fabrics throughout the dyeing operations thereon which includes the step of weaving into such fabrics during the weaving operation and at a predetermined place thereon, an indicator of predetermined characteristics localized at said place, said indicator being a fibrous glass yarn incapable of being dyed, and subjecting the fabric after weaving to a dyeing operation whereby the organic fibers are colored while the glass yarn remains unaffected so as to be clearly distinguishable visibly from the juxtaposed organic fibers and thereby serve to identify the dyed fabric.

2. The method of tracing and identifying organic skeins throughout the dyeing operations thereon, which comprises attaching to said skeins at localized points circumferentially thereof a leesing yarn of identifying characteristics, said yarn being composed of fibrous glass which is incapable of taking on the colors of dyes, subjectmg said skeins and attached leesing yarn to a dyeing operation in which the skein is colored while the leesing yarn remains unaffected, and then removing said leesing yarn after completion of dyeing.

3. The method of distinguishing different classes of organic textiles when dyed simultaneously together in the same vat, which comprises combining with each of said classes, yarns composed of fibrous glass incapable of taking on the color of the dyes, each class receiving glass 'yarns of characteristic features different from those of the other glass yarns, the glass yarns for each said class being visibly distinct from the others, and subjecting said textiles and combined fibrous glass yarn to a dyeing operation whereby the organic textiles are colored while the glass yarns remain unaffected to serve to identify the dyed textiles.
